✦ Synopsis


The mechanism of stereoregulation in polymerization reaction is discussed in terms of the two model cases: (i) the growing chain control mechanism, and (ii) catalyst control mechanism. These two mechanisms were observed to be operated in the stereoselective polymerizations of methyloxirane and of tert-butyloxirane.

* -isotactic sequences, and vice versa. No influence at all was observed from the chiral structure of growing chain end in determining stereochemical sequences in the polymer molecule.

Results of copolymerization between Dand L-monomer were found to be a useful experimental tool for elucidation of mechanism of stereoregulation.

## Abstract Oxiranes, such as glycidyl phenyl ether, benzyl glycidate, glycidyl methyl ether, and styrene oxide, were copolymerized with dicarboxylic anhydrides, such as succinic anhydride, phthalic anhydride, and maleic anhydride, by the action of an enzyme in a stepwise reaction to produce the co
